What is RVHD-2?
Rabbit Viral Haemorrhagic Disease (also known as RVHD, RHD, and VHD) is a highly contagious, deadly disease that can affect rabbits of all ages. There are two strains of the disease; RVHD-1 surfaced in the 1980s and RVHD-2 is a more recent development.
The disease is spread by myriad means - which is why house rabbits are not safe from it - including:
- Contact between rabbits and their droppings
- In the droppings of birds and insects
- Through airborne particles
- Contaminated surfaces
- Carried on hands, clothing, shoes, tyres and on other pets’ feet
RVHD symptoms include:
In some cases, sudden death is the first and only sign that a rabbit had contracted RVHD. Other signs include:
- Respiratory difficulty
- Loss of appetite
- Bleeding from the nose or mouth
Differences between RVHD-1 and RVHD-2:
RVHD-2 tends to develop slower, and rabbits will show symptoms for longer, which can include weight loss and jaundice from liver disease. The mortality rate seems to be lower for RVHD-2, however, it is still a killer disease. Another difference is the incubation period between the two strains, which is 1-4 days for RVHD-1 and up to 9 days for RVHD-2.
Treatment & prognosis:
Alun wants rabbit owners to understand the seriousness of this disease. RVHD is untreatable and almost always fatal – sometimes within hours – as it causes internal bleeding in major organs. Some rabbits may be offered fluid therapy and pain relief, but very few survive. Therefore, it is vital that your pets are protected.
How to protect your rabbits from RVHD
Rabbit vaccinations can be given from the age of five weeks, with boosters needed every year for life. The RVHD-1 vaccine is usually combined with one for myxomatosis; there is a separate RVHD-2 vaccine.
Alun advises that you can further help to protect your pets by;
- avoiding contact with other rabbits when you’re out and about
- making sure your rabbits are nowhere near any wild cousins
- changing clothes after going out and before interacting with your pets
- thoroughly washing your hands before and after handling your pets
You cannot stop insects and many other forms of transmission though, so rabbit vaccinations are a must. Book an appointment with one of our Vets and put your mind at rest.
